Transformed into the leader of an esoteric sect in Japan

"You have the bigger fist, so whatever you say is right!"

"It's all Yamauchi's own fault! It has nothing to do with us, how dare we provoke you!"

The Yamauchi men who had been blocking the way now opened a path for Kurosawa Shizuki as if they had seen a ghost. The passion that had been ignited by Yamauchi's secret techniques had completely cooled down.

"What are you bunch of trash doing here? Those who need medical attention, go to the doctor; those who need to go to school, go to school. Get out of here within five minutes, or you'll face the consequences." Kurosawa Shizuki's voice was soft, but it could be clearly heard by almost everyone present.

"Also, Mizushima's men, take your two leaders to the hospital. Their condition seems a bit bad." Kurosawa Shizuki hadn't forgotten about the unconscious Kanda and Mizushima. Even his underlings, who hadn't participated in any fighting, finally remembered their boss who had always been a bystander. They quickly lifted Kanda and Mizushima up and carried them out of the factory.

Kurosawa Shizuki couldn't be bothered with this bunch of good-for-nothings anymore. If the original owner's purpose in subduing these delinquents was to find Yamanouchi, then they had already lost their usefulness and there was no need to pay them any attention.

The remaining Yamauchi men, still conscious, rushed toward the factory exit one after another, as if Kurosawa Shizuki, who had beaten their boss half to death, was truly a ferocious beast that would devour anyone who dared to do so.

Soon, everyone unrelated was cleared out, leaving only Kurosawa Shizuki and Yamauchi in the abandoned factory. The air was so quiet it was suffocating. Once she was sure no one was watching her, Kurosawa Shizuki could finally get down to business.

Kurosawa Shizuki continued to drag the unconscious Yamauchi deeper into the factory, wanting to find a more secluded place where she could have a proper "talk" with Yamauchi Yuki, one that was less likely to be watched by others.

“Hahaha… This is really unexpected,” Yamauchi gasped weakly. “I never thought I would run into someone from the Black Sun here. I’m so unlucky.”

"If you're willing to tell me what I want to know now, it can save you some trouble." Kurosawa Shizuki glanced at the time on her phone. School started at eight o'clock, and she only had twenty minutes left. She had to resolve this quickly.

"What a joke! I know what kind of people you are," Yamauchi said through gritted teeth. "I'm not going to live today anyway, so why should I tell you anything?"

"You think too much of me, don't you?" Kurosawa Shizuki smiled very kindly. "Even when the fight got to that point, I didn't kill a single person. I'm very kind."

"You bunch of shadow-binders who eat people with your shadows, and you call yourselves kind? You'll do anything to feed the black beast! A bunch of vermin who only know how to cower in the shadows!" Judging from what Yamanouchi said, the Black Sun Cult seems to have a very bad reputation in the esoteric world.

"We're all in the same boat, so let's stop standing on our moral high ground and criticizing each other. Your Divine Age Society practices human sacrifice, turning people into mist, which is far more outrageous than what we do, isn't it? If we really bring that mist spring back to the world, it'll be a question whether even 10% of humanity will survive." Kurosawa Shizuki sneered.

“A brief death is only for a greater eternal existence. In the Land of Mist, there will be no more death and pain, and we will gain eternal freedom…” Yamauchi murmured to himself. “However, there will be no place for you filthy monsters to live in our divine kingdom. You will all be exterminated sooner or later. No shadows can linger beneath the red mist.”

Kurosawa Shizuki finally found an abandoned little dark room, which seemed to have been the gatekeeper of this factory. She dragged Yamauchi inside. If this were a small H-game, this kind of dark room might have a lot of treasured CGs.

However, Shizuki Kurosawa will ensure that what is about to happen will only become extremely brutal.

Kurosawa Shizuki was too lazy to waste words with this guy. As a nominal member of the Black Sun Cult, she was destined to have no common ground with the Generation of Gods.

Based on her experience playing the game three times previously, all esoteric organizations pursue their own transcendence and ascension, transforming current history into a history determined by the specific deity worshipped by the esoteric sect.

For example, the ultimate great achievement of the Black Sun Cult is to recreate the ancient Black Sun era, where a black ocean engulfs all things, a black sun never falls, black mud erodes the will of the planet, and humans and shadows merge to become new black matter life, where individuals are no longer distinguished from one another, and consciousness pursues infinite inspiration and freedom in the spiritual ocean.

The history determined by Wuquanzi seems to be called the Red Mist Era by the Association of the Gods. It is said to be a terrible era in which strange beasts roamed the world. Huge beasts roamed the human world, and the few remaining humans huddled in the red mist, barely surviving. The followers of the Association of the Gods believe that humans are a species that will eventually be eliminated, and the followers of the Association of the Gods seem to hope that they can eventually become "mist".

While there are both cooperation and conflict among different esoteric sects, ultimately, all esoteric sects are mortal enemies. This is because only one sect is destined to ultimately triumph, achieve great things, and establish a new era; only one deity can determine the course of history. However, whatever era the esoteric sects ultimately establish will undoubtedly be a terrifying apocalypse for humanity, the current rulers of the era.

"Hurry up and finish me off. Don't expect to get anything out of me. Our great undertaking is about to be accomplished, and I believe you will soon die a more miserable death than I did," Yamauchi said, leaning against the wall with a mocking and fanatical smile. "Did you really think that mortal punishments would work on me?"

“I’m sorry, but I’m sure you’ll tell me everything I want to know. I don’t need to ask.” Kurosawa Shizuki reached her hands toward Yamanouchi’s head, her wrists wrapped with black threads.

"What is this?!" In Yamauchi's horrified gaze, viscous black liquid emerged from Kurosawa Shizuki's collar and cuffs, crawled along her artistic arms, and finally fell onto Yamauchi's body.

"Damn it, damn it, damn it, it's actually a fourth-tier beast—ahhhhhh!" Yamauchi tried to struggle, but the black matter had already bound his hands and feet, pressed down on his throat, and quickly crawled up and down his body. Several black beasts burrowed through his skin, but no blood flowed out. The black matter quickly crawled up and down under his skin.

Finally, the writhing black matter coiled around his body, and the living black matter crawled to both sides of his cheeks, with terrifying tentacles standing up, and then burrowed into his ear canals, nostrils and mouth!

The black matter began to gradually encroach upon Yamauchi Yuki's territory.

The hostile esoteric cultists were an ideal target for Kurosawa Shizuki's experiments with the power of the black matter spirit.

He will become Kurosawa Shizuki's first shadow servant.

P.S. I'm trying to make the outline simpler and more straightforward. I struggle to write overly complex plots, and people aren't interested in them. It's true that writing more vignettes is much easier than writing complicated plots.

By the way, could you please give me some votes? I'm not expecting anything else, just some recommendation votes would be great.

Section 37, Chapter Thirty-Seven: Shadow Servants

[You have initiated a black matter erosion attack on Yamauchi Yuuki. Your black matter spirit growth has decreased by 0.5%. Current success rate: 93.56%.]

Holy crap, the Black Matter Erosion actually consumes Black Matter Spirit Growth Points? This one erosion is equivalent to eating three or four ghouls! Kurosawa Shizuki felt extremely pained. Her total Black Matter Spirit Growth Points were only less than three percent, and this one dropped to just over two percent.

I feel like I'm still a long way from the fifth stage. I guess I'll need to eat something big in the future.

Moreover, the black matter erosion actually had a success rate. Kurosawa Shizuki had never been confident in her own luck, so if she failed despite a success rate of over 90%, it would be too disastrous. Kurosawa Shizuki felt that failure would definitely not end well.

Less than a few dozen seconds after the black creature burrowed into the mountain's body, the desperate and frantic screams came to an abrupt end.

With his face contorted in pain, Yamauchi stared wide-eyed at Kurosawa Shizuki, his expression filled with resentment, determined to memorize her appearance in his final moments before death.

Kurosawa Shizuki looked at the motionless body of Yamauchi Yuki with apprehension. He lay stiffly on the ground. Five minutes earlier, she had confirmed that Yamauchi had stopped breathing and his heart had stopped beating; he was completely dead.

However, the dramatic changes that followed him never stopped.

The black matter rampaged unchecked within his body, transforming his still-human, fragile structure in a way that was beyond human comprehension.

First, it merges with the blood inside the mountain, making the mountain's blood as viscous as black mud.

Then it began to erode Shan's internal organs. You could see all sorts of strange protrusions appearing on Shan's body surface from time to time, as if countless small insects were crawling inside his body.

Finally, the limbs reacted particularly violently when the black matter flowed through Yamauchi's left arm, which had been completely mutated and injured by Kurosawa Shizuki. Kurosawa Shizuki witnessed Yamauchi's left arm begin to twist and deform continuously, sometimes resembling a lizard and sometimes growing fur like a wild beast. Finally, it stabilized its shape once again. The black matter undoubtedly won the battle against the alien god power belonging to the Age of Gods within Yamauchi's body.

Yamauchi's arm was restored to its original state once again, all the injuries were repaired, and it even became whiter and stronger, no longer as rough and clumsy as Yamauchi's original body.

Finally, the melanin began to erode Yamauchi's brain. Countless fine black blood vessels could be seen protruding and disappearing on Yamauchi's face, which was in a state of flux. The melanin was establishing a connection with Yamauchi's nerves, allowing Kurosawa Shizuki to easily uncover the secrets within Yamauchi's mind.

Yamauchi quietly opened his eyes. There was no longer a distinction between the whites and pupils in his eyes; they were now completely black, an unfathomable darkness. Then the darkness dissipated, and he became no different from a normal person.

The gruesome transformation seems to be finally over.

[Congratulations on completing the daily quest, "A Bite of Heijyo 1". You have obtained 1500 Nightmare Points, Shadow Servant - The Wishful Swordsman, and 1 Small Black Crystal.]

The notification that the task was completed sounded at just the right moment. It seemed that the system could indeed partially predict what Kurosawa Shizuki would encounter today. The system's power was becoming more and more magical in Kurosawa Shizuki's eyes.

With 1500 Nightmare Points, plus what she had left before, Kurosawa Shizuki now has over 2000 Nightmare Points. Nightmare Points are coming in exceptionally easily.

As for the so-called small black crystal, Kurosawa Shizuki looked at the black crystal that had somehow ended up in her palm. No matter how she looked at it, its shape resembled a miniature human finger.

The fragment of the Black Sun God Stone that Kurosawa Shizuki always wore on her chest seemed to shimmer with a dark light because of this suddenly appearing crystal, probably because people of the same origin would resonate with each other.

[Small black crystal, green quality, residue left behind by a creature from the Netherworld. Followers of the Divine Age sect implant it into their bodies, pursuing forbidden power after its mutation. Effects: Can be implanted into the body, granting a portion of the body localized mutation skills and exhibiting certain characteristics of a Netherworld creature; can be devoured by black spirits to gain growth; can be used as material for low-level rituals, with a certain chance to grant participating cult members multiple low-level Heart-attribute secret techniques.]

So the reason why Yamauchi was able to grow such a terrifying monstrous arm was because of this black crystal? Kurosawa Shizuki wasn't very interested in implanting this crystal into her body. She had no intention of growing such a terrifying monstrous arm, and even if she had that kind of arm, she would be defeated in a single round when fighting against her own black crystal.

"I guess I'll just use it to feed the dark spirit." Kurosawa Shizuki casually tossed the dark crystal toward the shadow behind her. The dark crystal sank into the shadow's mud without making a sound.

However, Shizuki Kurosawa felt a deep sense of satisfaction, like drinking a whole bowl of warm miso soup on a cold winter morning, making her feel warm all over.

[Your Black Matter Spirit has devoured a small Black Matter Crystal, increasing its fourth-stage growth rate by 0.84% ​​and its Nightmare Points by 306.]

This black crystal is far more cost-effective than just eating those low-level monsters! Kurosawa Shizuki finally saw a glimmer of hope for advancing her black spirit, which had never even reached 10% growth. If she could kill a few more cultists like Yamauchi Yuki who had implanted crystals, she might have a chance to advance to the fifth stage of the Longevity class sooner!

Looking at her current total Nightmare Points, 2368, Kurosawa Shizuki thought she could probably exchange for something in the system again. However, she suppressed her desire to buy, buy, buy. Instead of getting a bunch of beginner-level skills, she might as well save up Nightmare Points to improve her Void Blade Style level. Skills are more valuable than quantity. She also had the all-powerful Black Matter Spirit Body, so she didn't really need many other skills.

Perhaps she could consider exchanging for life skills like singing, literary writing, or music composition. Searching the system, most life skills were either white or green; while they wouldn't improve combat power, they would at least better help her as a plagiarist. Oh, and cooking should be prioritized! Kurosawa Ai kept pitifully saying that her older sister always cooked, and Kurosawa Shizuki was really looking forward to seeing her younger sister's reaction to the "glowing dishes" she would make after exchanging for these skills.

But these things aren't urgent; we can consider them slowly when we have more time later.

Finally, Kurosawa Shizuki began to observe the shadow servant she had just subdued.

[Congratulations on obtaining the Blue Shadow Servant, the Swordsman of Sorrowful Wish, Yamauchi Yuki, Rationality: 12, Spirituality: 8, Physique: 21...] The system notification continued to ring out, and Kurosawa Shizuki discovered that in her hidden cult panel, in addition to Kurosawa Ai's name, there was another name, Yamauchi Yuki.

His skills are basically the same as when he was alive, and he can still use his movements and words. However, because he no longer has crystals, he has lost that localized mutation function. His physique has also been strengthened, and he has gained several new characteristics:

[Shadow Servants. As shadow servants, they are under the absolute control of their masters, yet can act independently for extended periods, consuming only a minimal amount of the master's mental energy to maintain; shadow servants can infiltrate their masters' shadows at any time; shadow servants can self-repair within the shadows.]

[Life Link: As a servant of the Shadow, the Shadow has a life link with its master, a dark spirit. When the master suffers a fatal injury, the Shadow servant can draw upon the Dark Spirit's essence to rapidly revive the master.]

[Resurrection of the Dead: As long as the soul is preserved intact after death, the master can revive the deceased at any time by consuming Black Essence. The maximum number of revivals is three. Upon death, Black Essence crystals of corresponding quality will be left behind.]

[Netherworld lifeforms can switch between shadow and material states at any time. When in shadow state, they are not observed or affected by material lifeforms, and they can devour other Netherworld lifeforms to repair and grow.]

As expected of a skill awakened only upon reaching the fourth stage of the Dark Spirit Body, the Shadow Servant is indeed quite powerful. It consumes very little of its master's resources and can even save its own life. If Kurosawa Shizuki didn't only have four Shadow Servant slots available, she would have considered simply converting all the defeated enemies into Shadow Servant. With a wave of her hand, a shadow army would appear behind her, and the Shadow Servant would mercilessly beat up the enemies without her lifting a finger—just thinking about it was exhilarating.

Even if it's this Yamauchi Yuki, Kurosawa Shizuki will have to replace him sooner or later. He's a beast-like delinquent leader and doesn't have much of a look. If there's a chance in the future, Kurosawa Shizuki hopes to turn all her Shadow Servants into cute young ladies.

P.S., I changed the cover, but it seems to be the same as a book published at the same time. Oh well, this is probably what my little sister looks like in my mind, except that she has a fake leg.

I think it should be more attractive than the original cover, since it features black stockings.

Section 38, Chapter Thirty-Eight: The Bond Pill, the Amethyst Insect, and the Molting Club

However, even someone as oblivious as Kurosawa Shizuki had to admit that the transformation process was extremely uncomfortable. Indeed, just as Yamauchi had cursed before, Kurosawa Shizuki's dark matter was "eating people." Kurosawa Shizuki only planned to use this terrifying skill on her mortal enemies in the future.

What makes Kurosawa Shizuki even more terrified is that Yamauchi only underwent Kurosawa Shizuki's black matter modification and it produced such a violent reaction. So what is the current state of her body as the source of all black matter?

Kurosawa Shizuki could clearly sense that a strange, dark power flowed within her body like a river at all times, and if necessary, she could unleash this terrifying dark power at any time without restraint.

Now she finally confirmed the fact that her body was eroded by melanin to a much greater extent than Yamanouchi's.

Almost all the blood in her body was completely integrated with the melanin, to the point that it was indistinguishable from her own. In fact, it could be said that the melanin was always flowing in her body.

Arteries, meridians, brain, internal organs, and other vital organs that belong to the normal human body are all filled with black matter. Under normal circumstances, the original body should have died long ago, but now the black matter drives this body to run forever with its incredible power. The body that has been modified by the black matter has already transcended the human realm in every sense.

Kurosawa Shizuki thought of the "immortality" characteristic she had seen in the character panel belonging to the Black Matter Spirit. Could this so-called immortality be the result of combining the Black Matter with the human body to this extent? Could such immortality really be considered normal immortality? Rather than immortality, Kurosawa Shizuki felt more like a walking corpse controlled by the Black Matter.

Kurosawa Shizuki was certain that there was an invisible thread connecting her and Yamauchi Yuki. If she wanted, she could control Yamauchi Yuki to do anything as she pleased, like manipulating a puppet, and could even project her own will onto Yamauchi for a short period of time.

With a creaking sound, Yamanouchi's bones cracked as if he were being pulled by invisible threads, and he slowly straightened up in a backward-leaning posture.

Then he looked at Kurosawa Shizuki, whose unfathomable black eyes were particularly unsettling. His entire demeanor became incredibly gloomy, as if he were a living corpse that had just crawled out of the morgue.

Even though she knew that the person in front of her had become her puppet, Kurosawa Shizuki still felt a chill run down her spine. The dark energy was indeed a very ominous power, which allowed her to work part-time as a necromancer.

"Can you still speak? Do you remember who you are?" Kurosawa Shizuki tried to communicate with her shadow servant.

“I am Yamauchi Yuki, Master. Of course I remember who I am,” Yamauchi Yuki said in a completely calm voice.

“Hmm… then tell me about your background, and how you obtained the ‘medicine’…” Kurosawa Shizuki hesitated for a moment, “Wait a minute, it seems I don’t need to ask at all.”

By placing her hands on either side of Yamauchi Yuki's temples, Kurosawa Shizuki discovered that she could control the black matter within Yamauchi Yuki's body to permeate his consciousness at will. Yamauchi now had no secrets from her.

A strange, translucent black substance was easily extracted from Yamanouchi's brain with Kurosawa Shizuki's index finger. It contained memories from Yamanouchi's mind. The black worm crawled in Kurosawa Shizuki's fair palm. Kurosawa Shizuki suppressed her nausea and slapped the black worm into her forehead.

A vast array of memory fragments unfolded before her eyes, like a thick, heavy book, which she could browse and read at will. After being filtered by the black matter, the memories that Kurosawa Shizuki could read were not so complicated and disordered that they would overwhelm her consciousness.

Interesting. I didn't expect that the black matter could forcefully read minds. The black matter spirit is too omnipotent! Kurosawa Shizuki even wanted to praise the black sun.

Kurosawa Shizuki's deep blue eyes became incredibly empty. Countless images flashed through her mind like movie scenes. Kurosawa Shizuki didn't care who Yamauchi was, what his past stories and hardships were, or why he joined the Shindaikai. All she wanted now was truly useful information.

A few minutes later, Kurosawa Shizuki's pupils regained focus.
